LOOSE-LEAF DEVICE.

Specification of Letters Patent.

Patented July 16, 1918.

Applicationfiled February 8, 1917. Serial No. 147,372.

The present invention relates to loose-leaf devices, and its object isto provide a device of that character in which the leaf members may bevery securely held and into which they may be readily inserted and fromwh1ch they maybe readily removed; and further to provide in such adevice leaf members with pockets, of improved and economicalconstruction.

These objects are attained by, and the invention finds preferableembodiment in, the device hereinafter described and illustrated by theaccompanying drawings, in which Figure 1 is a view in perspective of aloose-leaf device; I

Fig. 2 is an end view of the back member and of the leaf membersthereof;

Fi 3 is a view in perspective of the back mem er;

Fig. 4: is a like view of a removable plate;

Fig. 5 is a sectional view of a pair of leaf members, each of which hasa pocket, and taken on a plane corresponding'to line 5-5 of Fig. 1; and,

Fig. 6 is a like View of a part of one of said leaf members taken on aplane corresponding to line 6-6 of Fig.1.

In the embodiment of the invention chosen for illustration by thedrawings and for detailed description in the body of this specification,the device is shown as a book having leaf-members with pockets adaptedto contain phonograph records. A back member 1 haslongitudinally-extending grooves 2, the sides of each such groove in theconstruction shown converging towardits mouth, so that the bottomportion of the groove is wider in cross section than its mouth. Eachleaf member 3 has a bight portion 4; adapted to be inserted into saidgroove and to be held therein against lateral removal by a rod 5 in thebight of the bight portion, the diameter of the rod together with thethickness of the bight portion being in said construction greater thanthe cross sectional dimension of the groove at its mouth.

In the structure illustrated, two leaf memtween them (Fig. 5).

bers have a common bight portion so that.

inserted are held in the grooves by plates 6,

at least one of which is removable, secured to the end of the backmember as by the screw 7, and extending across the ends of the grooves,thus covering the edges of the bight portions and the ends of the rods.When the plate is removed, the rods and bight portions may be slid out.The device is shown provided with covers 8.

The leaf members are formed with pockets 9 therein having closed edges10, 11, and bottoms 12 and adapted to contain phonograph records, theconstruction as shown being as follows: A sheet, as of paper, is foldedto form one edge 10 of the pocket at the free end of the leaf member,and the sheets edges at the opposite side are riveted at 13 to the bightportion or binding-edge portion 4 be- The lower end 15 of one fold 14 ofthe sheet is turned over and secured as by glue to the other fold 16 ofthe sheet to form the closed bottom of the pocket I (Fig. 6).

The invention being intended to be defined solely by the claims, is notto .be limited to or by details of construction shown or described.

What is claimed is:

1. In a device of the character described; a back member havinlongitudinally-extending grooves; leaf members having pockets adapted tocontain phonograph records and having bight portions adapted to beinserted into the grooves; and releas able means for retaining the bightportions in the grooves.

2. In a device of the character described;

a back member having longitudinally-extending grooves with sidesconverging toward the mouths of the grooves; leaf members having pocketsadapted to contain phonograph records and having bight portions adaptedto be inserted. into the grooves; and releasable means for retaining thebight portions in the grooves.

3. In a device of the character described; a back member havinglongitudinally-extending grooves with sides converging toward the mouthsof the grooves; leaf memnograph records and having bight portions ofsaid portions ends of the grooves and adapted to hold the ada ted to beinserted into the grooves; rods in t e bights of said portions andadapted to releasably hold the same in the grooves against lateralremoval. I

4. In a device of the character described,

a back member having longitudinally -extending grooves with sidesconverging toward the mouths of the grooves; leaf members having b-ightportions adapted to be inserted into the grooves; rods-in the bights ofsaid portionsand adapted to releasably hold'the same in the groovesagainst lateral removal; and releasable means for holding the bightportions and the rods against 1ongitudinal removal.

5. In a device of the character described; a back member havinglongitudinally-extending grooves with sides converging toward the mouthsof the grooves; leaf members having bight portions adapted to beinserted into the grooves; rods'in the bights and adapted to releasablyhold the same'in the grooves against lateral removal; and a removableplate'at the end of. the back member extending across the open bightportions and the rods against longitudinal removal.

6. In a device of the character described;

form an edge of the pocket at the free end of said member opposite thebinding-edge portion and by rivetm the sheet to the binding-edge portiontween them,

7. In a device of the character described;- a leaf member having abinding-edge por-.

tion and a pocket made by folding a sheet to form an edge of the pocketat the free end the edge portions of of said member opposite thebinding-edge portion and by riveting the edge portions of the sheet tothe binding-edge portion between them,

and by folding thebottom portion of one fold of the sheet and securingthe same to the other fold-of the sheet.

' In testimony whereof I have hereunto set my hand, in presence of twosubscribing witnesses, at Grand Rapids, Michigan, this 5th day ofFebruary, A. D. 1917. I
